Title: Vibrator motor
Inventor: OKUYAMA TOSHIHIDE
IPC: H02K7/075
Filed: 1993-04-12
Abstract: PURPOSE:To avoid a strong friction caused by a thrust force and suppress a power consumption by a method wherein a magnetized part is provided at least on one of a rotary member side composed of a rotary shaft, a rotor, a weight, etc., and a stationary member side composed of a casing, a stator, etc., and an attracting part which attracts the magnetized part is provided on the other side. CONSTITUTION:A circular iron piece 7 is attached to the rear end of a commutator 50. A cup-shaped iron box 60 is attached to the inner surface of a casing 90 facing the iron piece 7 and a magnet 6 is fitted into the iron box 60. A gap is provided between the iron piece 7 and the magnet 6. Further, magnetic poles on the rear surface of the magnet 6 are exposed on the edge part of the iron box 60 and both the N and S poles are arranged concentrically on the rear surface of the magnet 6. If a rotation to the direction of an arrow is given in this state, a thrust force A is applied to a rotary shaft 3 but the attraction force of the magnet 6 is so applied as to cancel the thrust force A, so that the horizontal movement of a rotor having a weight is suppressed and a friction caused by bringing a shim 30 into contact with the end part of a bearing 40 can be reduced.

IPC: H02M7/72
Filed: 1988-05-06
Abstract: PURPOSE:To continue operation safely even upon system voltage drop by correcting an output power command value corresponding to a measured system voltage. CONSTITUTION:A system 1 is linked through a link circuit breaker 5 with a power storage system. An AC/DC converter 2 is connected with a secondary cell 3a at the side of the power storage system in order to communicate power between them.

Assuming rated system voltage is Vn and measured system voltage is Vm, an output command value P'ref=Vm/Vn.Pref is provided to the constant power controller 4. By such arrangement, overload can be prevented even upon system voltage drop.

Title: Toothpaste composition
Inventor: SETO SHINICHI
IPC: A61K8/81
Filed: 1983-06-17
Abstract: PURPOSE:To prepare a toothpaste composition having excellent shape-retainability and low stringiness, and giving agreeable feeling to the palate, by compounding a cationic polymer together with silica. CONSTITUTION:The objective toothpaste composition is obtained by compounding silica and 1/5-1/1,000pts.wt. (based on 1pt. of silica) of a cationic polymer (e.g. cationized cellulose, dimethyldiallylammonium chloride, etc.). The addition of the cationic polymer causes the flocculation and gives a highly thixotropic gel. Accordingly, the necessary amount of other binder can be reduced and the shape-retainability and the stability of the toothpaste composition can be improved without using a large amount of binders. In the case of using igneous silica as the binder, the characteristic astringent taste can be decreased according to the decrease in the content of the silica. A transparent toothpaste composition can be prepared when a silica-based abrasive is used as the silica and mixed with a transparent vehicle.

Title: Semiconductor integrated circuit device
Inventor: IKEO HARUYUKI
IPC: H01L21/822
Filed: 1985-05-24
Abstract: PURPOSE:To inhibit a latch-up phenomenon by disposing a constant-voltage generating circuit at a position where most distant from a CMOS along the outside of a wiring region in the periphery of a chip in a Bi-CMOS type semiconductor integrated circuit with a constant-voltage generating source. CONSTITUTION:Constant-voltage generating circuits VG1 and VG2 from which leakage currents are easy to be generated because currents the flowed stationarily and the circuits are operated are arranged where most separate from an X decoder circuit X-DEC constituted by a CMOS circuit, Y decoder circuits Y-DEC 1, Y-DEC 2 and a timing generating circuit TG with a CMOS circuit. An internal between bonding pads P2 and P3 is made wider than that between normal pads in the VG1, and the bonding pads are arranged so as to be disposed in an approximately lateral one row with pads P1-P11 in the VG1. Accordingly, parasitic thyristors existing in the decoder circuits are difficult to be triggered by leakage currents generated by the VG1 and the VG2, thus inhibiting a latch-up phenomenon.

Abstract: PURPOSE:To improve the precision of the estimated control by varying the set opening degree on the basis of the result of the judgement of the inclination of a road before the estimated control, in the estimated control for opening a throttle to a set opening degree before the throttle opening/closing control on the basis of the car speed deviation. CONSTITUTION:When the aimed car speed is set by turning ON a setting switch 15b during the traveling of a vehicle, if the actual car speed detected by a car speed sensor 18 is over a prescribed value, the constant speed traveling for adjusting the opening degree of a throttle by drive-controlling a servomotor 20 according to the car speed deviation is memorized. Though the estimated control for opening the throttle at a set opening degree which is previously set according to the car speed is performed, the inclination of a road before the estimated control is judged on the basis of the data of the throttle opening degree for the car speed obtained by an automatic transmission, and the above- described set opening degree is varied on the basis of the result of the judgement. Then, the existence of a cancellation signal is judged, and if the cancellation signal does not exist, constant speed traveling is executed.

Abstract: PURPOSE:To realize improving the effect of lubrication for sliding face of an apex seal by providing, by means of photoetching method, a large number of oil holding concave parts with nearly letter U-shaped section on a trochoid face of a rotor housing. CONSTITUTION:Oil holding concave parts 14..., independent of each other with a nearly letter U-shaped section and also a circular opening, are engraved by means of photoetching method covering the whole trochoid face 1a of a rotor housing 1 lengthwise and crosswise at a constant pitch interval.
